Subject: [PATCH 0/3] Conversion to __atomic builtins
Date: Sat, 12 Nov 2011 11:07:00 -0000	[thread overview]
Message-ID: <1321080394-16180-1-git-send-email-rth@redhat.com> (raw)

Well, most of it.

The first patch removes two avoidable warnings in rs6000.md.
It seems like we could avoid many more of the remaining, but
those are harder; this one was obvious.

The second patch is a build error.  It has appeared on this
list previously, but not yet applied.

The third implements the atomic operations (mostly) as described in

 http://www.rdrop.com/users/paulmck/scalability/paper/N2745r.2011.03.04a.html

There are a couple of instances in which the paper doesn't cover the
handling of memory_model_consume, and I made a best guess.  These
are indicated by /* ??? */ markers.  I would be obliged if someone
could verify what's supposed to happen in these cases.  I attempted
to handle them conservatively.

Tested on ppc64-linux, with a reduced set of languages.  I could
not get libjava to build for some reason.  Missing symbols linking?

Please double-check.
